2. Claims.

The present invention relates to certain new and useful improvements in proportioning dispensers, generally speaking, and has reference in particular to a structurally unique mechanical dispenser which is free of moving parts and is primarily adapted to be attached to the neck of a disinfectant or deodorant containing bottle, which when properly suspended in an inverted position and at the proper elevation, serves to automatically dispense a nominal amount of the disinfectant into the water of a flush tank.

As the title of the invention and preceding general statement reveal, it is an object of thepresent invention to structurally, functionally and otherwise improve upon similarly constructed and performing prior art tank-type dispensers and, in doing so, to provide a simple, practical and economical adaptation which will fulfill the manufacturing requirements of manufacturers and the expected needs of users.

As is self-evident, the over-all means, the hanger bracket, disinfectant containing bottle, and novel dispenser, is expressly designed for use in a conventional type flush tank, the dispenser being automatically operable and controllable by the rise and fall of the water in said tank. Briefly, the dispenser is a simple screw-type cap for a threaded neck bottle and this is capped over and communicatively connected with the neck and is characterized by an elevated bottom and encompassing wall portion defining an air trapping, confining and compressing pocket, said bottom having a restricted air intake port communicating with said pocket, a compressed air ascending duct in said cup registering with said port and provided with a restricted airdischarge port opening into the receptacle portion of said cup, a disinfectant conduit also in said cup having a restricted intake opening adjacent the interior surface of said bottom, the wall of said cup, at the upper end of said conduit having a disinfectant overflow and dispensing port, whereby when the water in said tank rises, after the tank has been customarily flushed, air is trapped and compressed in said pocket, is forced into the cup by way of the intake port, duct and discharge port, exerts pressure upon and compresses the disinfectant in the cup and forces a proportional amount of the disinfectant up the conduit and discharges the same into the tank water by way of said dispensing port.

The dispenser preferably includes an integral neck which extends and depends concentrically into the stated cup and terminates close to said bottom, whereby a minimal amount of the disinfectant is contained in said cup in readiness for discharge at the time the water in I the tank, after having been flushed, rises and functions in the stated manner to dispense or eject the predetermined amount of disinfectant into said water.

Other objects, features and advantages will become more readily apparent from the following description and the accompanying sheet of illustrative drawings.

In the drawings wherein like numerals are employed to designate like parts throughout the views:

Figure 1 is a fragmentary sectional view of a flush tank showing the disinfectant or equivalent bottle or container, the improved dispenser, and the bracket means for hanging or suspending the means for operation in the tank water;

Figure 2 is a view similar to Figure 1 and which shows' the tank water at normal level with the dispenser submerged therein and while the disinfectant is discharged into the water; and

Figures 3 and 4 are sections on the horizontal lines 33 and 4--4Iof Figure 1 looking in the direction of the arrows.

In the drawings the flush tank, which maybe of any conventional construction is denoted by the numeral 6.

The flush water is denoted at 8. Other details of the tank construction are thought to be unnecessary and are,

The neck is here shown as externally screw threaded as at 22. It is within the realm of the invention to provide any suitable container means with or without a neck and with the neck so constructed as to accommodate the attachable and detachable dispenser device 24.

The bottle may be of appropriate commercial plastics suitably shaped and sized and also the dispenser 24'may be constructed of commercial plastics although the demonstrating devices used have been of non-corrodable metal. It is preferred that the dispenser shall be. in

the nature of a screw cap so that it serves as a suitable It is closure for the bottle when the latter is upright. generally cylindrical in cross-section and has an attaching portion 26 which is screw threaded and is therefore attached in the manner illustrated in the, drawing. Being substantially hollow, this cap when inverted becomes a disinfectant receiving and dispensing cup. The wall of' the cup is denotedat 28 and at the upper end thereof in one side there is a disinfectant discharge port 30. *It will be noticed in particular that the bottom, which is essentially imperforate, is denoted at 32 and that it is elevated whereby the depending portion 34 provides an encompassing skirt and the two features define an airtrapping, concentrating and compressing pocket 36. Since this compressed air is intended to enter the cup there is a compressed air intake provided at 38 and this registers with a restricted vertical channel-like air duct 40. At the upper end of this there is a port 42 communicating with the interior of the cup. There is a similar diametrically opposite channel-like member 44 provided and this is distinguished as a disinfectant channelling and discharge conduit and it is in communication, as shown with the discharge port 30. It will be noticed that the lower end of this conduit is spaced above the bottom and provides a disinfectant inlet 46 (Fig. 2). This cup is provided with an extension neck 48 and this is in line with the bottle neck and is concentric within the cup and has its lower end terminating in spaced relation above the bottom and also above the plans of the disinfectant inlet for port 46.

This dispenser 24 provides, as already stated, a handy cap for the bottle and permtis the same to be filled or replenished when the supply has been exhausted. Any deodorant, disinfectant or germicidal liquid may be used, as is obvious. The invention is, of course, in the bottle or equivalent container 10 with or without a neck, and the special dispensing device 24 which is connectable with the neck. When the dispenser-equipped bottle is in verted and suspended in the tank the dispensing device. will immerse itself into the water 8 as shown in Figure 2 r Patented June 24, 1958- An appreciable portion of the disinfectant will gravitate into the cup and a partial vacuum will .be' formed be tween the head of the disinfectant column and the space above it in the bottlein an obvious manner to trap the disinfectant inthecup in the manner shown in Figure l and'to prevent passage through'the discharge po1t30.

Assuming that the flush tank has been operatedand the flush water has receded to flushthe bowl, itwill build back up in the customary manner and as the water rises in the tankit will compress air in the pocket 36 and Will force the air through the port 33 up the duct 46 and into the. cup space 59 by way of the port 42. This will exert pressure on the disinfectant in the cup, will compress it and force a limited amount up the conduit 44 by way of the inlet 46 and the same will be discharged in a limited amount by way of the discharge port 35), as

brought out in Figure 2. The amount to be dispensed I can be controlledby the size of the pocket 36, duct and conduit and other companion parts.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:
